  • System and method for Ec/Io access screening in a CDMA network
    Patent number: 8687494
    Abstract: Provided are system and method for performing access screening in a CDMA network. In one embodiment, the method comprises comparing a strength of a reference pilot specified in an origination message (“ORM”) received from the mobile unit to at least one of an upper pilot strength threshold (“UPST”) and a lower pilot strength threshold (“LPST”); responsive to the reference pilot strength failing to exceed the LPST, redirecting the mobile unit; responsive to the reference pilot strength exceeding the LPST but failing to exceed the UPST, determining whether an additional pilot is reported having a strength greater than that of the reference pilot; and responsive to a determination that no additional pilot is reported having a strength greater than that of the reference pilot, redirecting the mobile unit.
